DESCRIPTION
ruby-build provides a simple way to compile and install different versions of Ruby on UNIX-like systems.
ruby-build downloads, builds and installs the Ruby version specified in a definition into a prefix directory. Definitions can be chosen

rbenv(1) users can also use the provided rbenv install command, which installs Rubies into the rbenv directory.
